Been there, done that. After you swap it (should you find it is
backwards), protect your ears by turning down the audio first. ;-).
HNY to all!

Hi
Double check T7. Make sure the green winding is in 1 and 2 and the red
winding is in 3 and 4 closest to the IC U12. If it is backwards the
sensitivity will be low, the audio will be low and the AGC will not work
properly although everything else will appear OK.

Subject: [Elecraft] A question about low sensitivity
Hi guys,
Been a while since I last kept up with the list. You were a great
source of help back when I built K2 #1133. Now I have #5226 and have
completed the second section of construction. The receiver works, I can
hear stations on 40. Yesterday I listed to Mid-Cars, Southcars, and
Eastcars. But they were only moderatly loud and I had AF gain full out.
On the IC-756 Pro they were booming.
On the radio I thought the AGC voltage might have been too high. 3.80
volts on the nose. T-34 tunes very well, as do L-1 and L-2. Every other
test and alignment to this point was well within specs. Any ideas as to
why it is not hearing well? Or should I not be concerned at this stage of
construction and press on to stage 3.
